Total back support

Many of Mirra's adjustments are passive, requiring no effort to operate. The patented TriFlex back, for example. This one-piece, pliable backrest naturally flexes and adjusts to your shape, height and motion.

The backrest features a passive PostureFit contour for superior lower-back support and comfort when you sit upright or forward at a computer.

Mirra is aerated so your skin temperature stays constant and moisture can move away from your body.

To support your entire back as you move throughout the day, the various geometric shapes in the TriFlex back create flex zones in the thoracic, lumbar and sacral regions.
